How to Sign Up for Los Angeles County Emergency Alerts Before the Next Disaster
How do I sign up for emergency alerts in Los Angeles County?
Los Angeles County residents can register for the county's address-based emergency notification system, called Notify LA, through the LA County Office of Emergency Management at lacounty.gov/emergency. Registration is free and takes about five minutes. You enter a street address and attach phone numbers or email addresses to receive alerts targeted to that specific location during emergencies.
Does Notify LA cover all cities in Los Angeles County?
Notify LA covers unincorporated Los Angeles County and many incorporated cities within the county, including the City of Los Angeles. However, some cities within LA County may operate separate or supplementary alert systems. Residents should confirm with their city's emergency management or public safety office whether their city participates in Notify LA or uses a different notification platform.
What's the difference between a Wireless Emergency Alert and Notify LA?
Wireless Emergency Alerts are pushed automatically by the federal government to all cell phones in a geographic area and require no sign-up. Notify LA is Los Angeles County's opt-in system that sends targeted alerts by registered address, meaning it can notify you about an evacuation order or warning specific to your neighborhood or zone rather than a broader region. Both systems can be active during the same emergency.
Can renters in LA County sign up for Notify LA, or is it only for homeowners?
Any resident or person who regularly spends time at a Los Angeles County address can register with Notify LA, regardless of whether they own or rent their home. Registration is address-based, not tied to property ownership. Renters, especially those in wildfire-prone areas like canyon communities or foothill neighborhoods, are encouraged to register the same way homeowners do.
How do I find my evacuation zone in Los Angeles County?
The LA County Fire Department maintains an evacuation zone map that residents can look up by address through lacounty.gov or the department's Ready! Set! Go! preparedness program. Knowing your zone in advance helps you respond faster when an evacuation warning or order is issued, since official alerts and broadcasts reference zone designations rather than just street names or neighborhood boundaries.
Los Angeles County has lived through enough wildfires, earthquakes, and flash floods in recent years that emergency alert sign-up has moved from a nice-to-have to something officials actively push residents to do before the next event. The county runs its own notification system on top of the state and federal layers, and the sign-up process is specific enough that it's worth walking through exactly how it works for LA County addresses.

What Systems Are Actually Covering You
When an emergency hits, three layers of alerts can reach you. The first two are automatic: Wireless Emergency Alerts (WEA) are pushed directly to cell phones by the federal government and require no action on your part, and the state's emergency broadcast system interrupts radio and TV. The third layer is LA County's own system, called Notify LA, which is operated through the county's Office of Emergency Management. This is the one that sends targeted alerts by address, so it can reach you about a fire burning in your specific neighborhood or a mandatory evacuation order for your exact zone. It does not activate automatically. You have to register.
Notify LA is the county's primary opt-in emergency notification platform. It lets residents register a home address, a work address, or multiple locations, and attach multiple contact methods, including phone calls, texts, and email, to each location. That address-based targeting is what makes it meaningfully different from a generic alert you'd get by following a county Twitter account or waiting for a TV broadcast.
How to Register With Notify LA
Registration is handled through the LA County Office of Emergency Management's website at lacounty.gov/emergency. From there, residents can find the Notify LA registration link. You'll enter a street address, then add the contact methods you want used for that address. Most people add both a cell number for texts and a call-back number, since different alert types or network conditions during an emergency can affect which one gets through faster.
You can register more than one address, which matters if you spend time at a second home, a parent's house, or a workplace in unincorporated county territory. Keep in mind that Notify LA covers unincorporated Los Angeles County and many cities that have opted into the system, but some cities within LA County operate their own independent alert systems. The City of Los Angeles, for example, uses the same Notify LA platform. If you live inside an incorporated city, it's worth confirming with your city's emergency management or public safety office whether that city participates in Notify LA or runs a separate system.
Registration takes about five minutes. After you submit, you'll typically receive a confirmation message to the number or email you provided. If you don't get one, log back in and verify your contact entries saved correctly.
Wildfire Evacuation Zones and How to Find Yours
Separate from alert sign-up, the county uses a zone-based evacuation system organized around Evacuation Zones rather than just neighborhood names. These zones are identified during an emergency in alerts and on official broadcasts, and knowing your zone ahead of time helps you move faster when an order drops.
The LA County Fire Department maintains a zone map that residents can look up by address at lacounty.gov or through the Ready! Set! Go! preparedness program the department runs. That map will show you whether your property falls in a zone that has historically been subject to evacuation warnings, which is especially relevant for hillside, canyon, and foothill areas in the county. The map is a planning tool, not a real-time fire tracker; for active incidents, the county uses its emergency management page and Notify LA alerts.
Other Alert Channels Worth Setting Up
Notify LA handles address-based alerts, but a few additional channels are worth setting up alongside it. The LA County Office of Emergency Management maintains official social media accounts and publishes situation updates during active events. The county's 211 line also activates as an information resource during declared local emergencies, routing callers to evacuation center locations, shelter information, and other assistance.

For earthquake-specific alerts, California's ShakeAlert early warning system pushes notifications through the MyShake app, operated by UC Berkeley and the California Governor's Office of Emergency Services. This is a state-level system, not county-specific, but it's designed to give a few seconds of advance notice before shaking arrives, which can be meaningful during a significant event. It's worth having both Notify LA and MyShake active on a phone used regularly.
Keeping Your Registration Current
A registration entered three years ago with a phone number you no longer use won't reach you when it matters. The county's Office of Emergency Management recommends reviewing and updating Notify LA contact information periodically, especially after a move, a phone number change, or any time you add a location you want covered. There is no fee to register or update.
If you rent, you can still register your address. Notify LA registration is open to any resident or person who spends regular time at a Los Angeles County address, not just property owners. Renters in wildfire-prone areas of the county, particularly in the Santa Monica Mountains, the foothills east of Pasadena, and canyon communities throughout the Santa Ana corridor, are as exposed to evacuation orders as any homeowner and should register accordingly.
This is general public safety information, not legal or emergency management advice. For current Notify LA registration, zone maps, and emergency preparedness resources specific to Los Angeles County, visit the LA County Office of Emergency Management at lacounty.gov/emergency. For active emergency incidents, monitor official county and city channels directly rather than relying on third-party sources.
